The Importance of Aerobic Energy System Efficiency for On-Court Tennis Performance

The aerobic energy system can contribute to enhanced performance during a tennis match or training even though tennis is anaerobic energy system dominant but steady-state jogging is an ineffective training method in optimizing aerobic energy system contributions. When one takes a look at the tennis sports analysis then it becomes evident that, from an energy...
Tennis Sports Analysis: Avoid Wasting Time During Training

Tennis Sports Analysis: Avoid Wasting Time During Training

The purpose of a sports analysis is to determine what a tennis player must be able to do in order to have success and design a training program accordingly. For example, we want to make sure that the athlete is not impeded by anything, which is why we do the analysis of limitations! When you...
Aerobic ATP Production & Energy System Efficiency

Aerobic ATP Production & Energy System Efficiency

Aerobic ATP production, which occurs predominantly during prolonged low-moderate intensity exercise, is the oxidation (breakdown) of glucose/glycogen (called glycolysis), lipids (triglycerides; called lipolysis), and proteins (amino acids; called proteolysis) into acetyl CoA, which enters the Krebs Cycle, where hydrogen removal occurs and the electron transport chain inside the mitochondria of the muscle cell provides the...
Why Jogging Is A Waste Of Time For Tennis Conditioning

Why Jogging Is A Waste Of Time For Tennis Conditioning

Many tennis coaches require their players to include jogging into their regular training program in order to maintain or enhance endurance capabilities but from a conditioning standpoint continuous steady-state jogging is inefficient and hence a waste of time. There are more effective training components, such as interval training, that allow the athlete to improve additional...
Glycolysis: Glucose Breakdown Provides Energy

Glycolysis: Glucose Breakdown Provides Energy

Glycolysis, the “splitting of glucose”, is the breakdown of glucose or glycogen in order to provide ATP, which occurs in the liver and in the sarcoplasm of muscle cells. Glycolysis is the energy system that predominantly provides energy for higher-intensity activities lasting 15-90 seconds and it provides a net gain of 2-3 ATP. The initial...
ATP-CP Energy System

ATP-CP Energy System

The ATP-CP system consists of two energy storage reservoirs: ATP (adenosine triphosphate) Creatine Phosphate (CP) ATP The primary energy reservoir is ATP. ATP storage capacity in the body is 80g-100g and provides energy for maximal output for 1-3 seconds, depending on exercise intensity and the individual’s body size (bigger people store more energy and can...
Biological Energy Metabolism: ATP Production

Biological Energy Metabolism: ATP Production

ATP (adenosine triphosphate) is the immediate source of energy for muscle cells. ATP consists of three parts: adenine ribose three linked phosphates ATP Synthesis During ATP synthesis, an anabolic reaction, the enzyme ATP synthase facilitates the assembly of this high-energy bond, energy is stored, and can be used to perform work when needed. ADP +...
